San Francisco, Calif. – May 26, 2011 – Pacific Crossing, a wholly owned subsidiary of NTT Communications Corporation and operator of the transpacific submarine cable system PC‐1, has completed repair on the PC‐1 North route which links Ajigaura, Japan with Harbour Pointe, Washington. The North and West routes of PC‐1 were damaged during the Tohoku Earthquake on March 11, 2011. The West route is expected to be
restored in late June.

Pacific Crossing is experiencing exponential demand for bandwidth on the PC‐1 cable system due to the industry leading low latency it offers between the United States and Japan. To keep ahead of customer demand, the cable restoration is accompanied by an upgrade of the system capacity and the enhancement of the company’s Ethernet service offering. Following the upgrade of the PC‐1 system in 2010, which pushed the lit capacity of the cable over the 1.3Tbps (terabits per second) mark, Pacific Crossing has now added additional wavelengths to boost transpacific capacity to 1.8Tbps.

“Pacific Crossing has successfully recovered its service on PC‐1 North route despite its extensive damage near the epicenter of the Tohoku earthquake on March 11,” said Mr. Takahiro Sumimoto, chief executive officer of Pacific Crossing. “The PC‐1 North route not only recovered from the earthquake, but we increased capacity to support further traffic growth, especially for financial industry customers who deploy time sensitive applications on our cable systems.”

As an NTT Communications company, Pacific Crossing provides the highest quality network infrastructure with the lowest latency between the United States and Japan, including extensive backhaul and Internet networks at both ends. Mr. Sumimoto added, “We will continue the restoration work on PC‐1 West until we fully recover our cable system. Pacific Crossing will keep investing in our network infrastructure and services in order to further strengthen our high quality offerings.”

Pacific Crossing owns and operates the transpacific, subsea fiber‐optic network ring, PC‐1, connecting the United States and Japan. The 21,000km PC‐1 submarine cable system offers the highest reliability and the lowest latency across the Pacific. Supported by extensive backhaul into major U.S. and Japanese cities, Pacific Crossing’s infrastructure offers seamless interconnection to virtually every major international network operator for onward global access. The company delivers state‐of‐the‐art capacity and managed network services at competitive prices to a growing customer base of carriers and media and information transport‐intensive enterprise customers. The company is registered in the USA and Japan, with principal
offices in San Francisco, United States and Tokyo, Japan. For more information, please visit www.pc1.com.
